| Abstract: | In this paper,the uniform dispersion of nanometer-SiO_2 in epoxy resin was studied.The influence of ultrasonic-wave oscillations and ultrasonic dispersion time on the mechanical performances of nanometer-SiO_2/EP composite was discussed.SEM indicates that the process of supershear and ultrasonic-wave dispersion was much better than single supershear.Through testing machine,the composites' mechanical performances had been tested.The reinforcing and toughening function of nanometer-SiO_2 had been furtherly proved. |
